If someone doesn't like the celebrations, they can get up and leave once the horn sounds. Or if they're at home, they can change the channel when the game is over. If people are upset and don't follow the Hurricanes anyway, why would the Canes care?
I think it's a bit odd because it's very different, but find it entertaining. If the added entertainment sells some extra tickets in Carolina and helps players bond, there's nothing wrong with it. Different teams have different gimmicks... Columbus shoots a cannon for goals, Detroit used swing an octopus, Nashville has a list of chants and taunt the hell out of opposing goalies. Even Vegas has turned the game experience into a very Vegas-like show. Good on the Hurricanes for coming up with something unique.
